数字读数模式是一种操作员模式。 数字读数模式帮助维修技师对传感器输入进行故障诊断和排除。 输入向四表组模块的仪表提供信息。 数字读数模式将仪表在正常模式下显示的信息更精确地显示出来。 系统标识符和系统数值都在六位数显示区域滚动。 系统标识符识别正在六位数显示区显示的系统。 要将系统标识符和对应仪表进行匹配,请参阅1"系统识别符"的表格和图示2。

注: 在某些机器型号的自定义应用程序会滚动到系统标识符 GA-5 和 GA-6。 这些系统标识符代表仅显示在六位数字显示区域中的机器系统信息,仪表不代表这些信息。

只有显示在六位数显示区域的系统仪表是运行的。 所有其他四仪表组模块中的仪表被关闭。 仪表指针将向最左边位置移动。

当你进入数字读数模式时,六位数显示区将显示系统 GA-1 的信息。 显示器短时显示系统标识符。 显示器在六位数显示区显示相应系统的值。 瞬时按下操作员模式开关能够滚动显示仪表。 快速拨动操作员模式开关。 当维修输入接地时,所有系统将滚动显示在显示器上。 这将显示系统标识符。 当所需系统出现时,从维修输入与接地断开,从而停止滚动。 六位数显示区瞬时连续显示系统标识符。 然后,六位数显示区显示系统值。 这时系统显示处在保留状态。 当系统处在保留状态时,系统的数值仍在继续更新。
